Safety Considerations

• Read this document for information on installation, handling,
mounting, general product specifications, and operation of this
product. These installation instructions contain important
information on handling the instrument.

• Working safety requires that all safety instructions and work
instructions are observed.

• Observe the relevant local accident prevention regulations and
general safety regulations for the range of use of the instrument.

• The installation instructions are part of the product and must
be kept in the immediate vicinity of the instrument and readily
accessible to skilled personnel at any time.

• Skilled personnel must have carefully read and understood the
operating instructions before any work begins.

• The Bulletin 837T-D is a temperature switch that converts
temperature into an electrical signal indoors and outdoors. The
device has been safely built with state-of-the-art technology and
meets the applicable requirements and EC directives. It can,
however, be a source of danger if used incorrectly or for
anything other than the designated use.

• Qualified individuals are required for installation and
commissioning. Failure to comply results in personal injury or
equipment damage.

• Before installation, commissioning and operation, be sure that
the appropriate temperature switch has been selected in terms of
range of measurement, design, and specific conditions of
measurement.

Recommended Installation for Optimal Performance

a. Installation at angle pieces, against the direction of flow
b. Installation in smaller pipes, which are inclined against the

direction of flow

c. Installation vertical to the direction of flow.

(1) At high medium or ambient temperature, helps confirm (by suitable measures) that the instrument case temperature does not exceed 80 °C (176 ° F) in continuous operation. The temperature is a measured hexagon of the

process connection. At medium temperatures (above 80 °C [176 °F]), the thread must not be immersed into the medium. The permissible ambient temperature is limited to -20…+40 °C (-4…+104 °F) at the high temperature

option.
(2) High temperature models are only available in 100 mm (3.94 in.) or greater probe lengths. It includes compression fitting that is approximately 55 mm (2.16 in.).
(3) The mounting situation (immersion depth, sensor length, operating conditions) determines the accuracy. This situation is especially the case for large temperature gradients between the environment and the mediu m.
(4) Absolute value of temperature.
